A System Dynamics Approach to Mine Modelling and Cut-Off Grade Management
By Larsen E. R
We discuss the concept of optimal cut-off grade policies and their advantages in terms of maximisation of net present value of mining operations. There are indications, however, that such optimal po

A systematic approach of sample selection to predict processing performance of an ore body
By K Tungpalan, E Wightman, M Edraki, E Manlapig, L Keeney
The depletion of easily mined high-grade ore bodies resulted in the industry having to exploit lower grade, complex resources (Albanese and McGagh, 2011; Darling, 2011; Randolph, 2011). The trend is n
